Anyone knows who made the music or if will be available?

Try google....Score is composed by Blake Neely. I would not actually look for a release. Who knows, but a lot of his never get an official release....

The series only debuted yesterday, as far as I know, so it will take a while for something to pop up.

Ok, but knowing it is blake neely we can expect more samples at his website :D

Don't bet on it. His site has not been updated in months. He says he will, but updates are rare. So I really would not count on that at all. Some of his stuff he is not allowed to post (like Pan-Am) due to network restrictions.

Blake Neely has posted samples for the first two episodes on his site @ 192. I am editing as I type.
